  3. 2. Electronic states in semiconductor double quantum dots and quantum rings - Theory and tight-binding modeling

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Calle Stenberg; [2021]
    Nyckelord :double quantum dots quantum rings tight-binding aharonov-bohm g-factor enhancement InAs; Physics and Astronomy;

    Sammanfattning : In recent experiments on semiconductor nanowires and quantum dots, enhanced g-factors up to several times the bulk value have been measured [1] [2]. The enhancement is attributed to orbital contributions g∗orb to the effective g-factor g∗ = g∗spin+g∗orb from the coupling of the high angular momentum ring-like states to the magnetic field.

  4. 3. Warpage Prediction of Electronic Underfill Components During Curing

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :David Lindblom; [2021]
    Nyckelord :Warpage; viscoelastic;

    Sammanfattning : To ensure the shelf life of a semiconductor, the integrated circuits are usually embedded in an epoxy molding compound (EMC) to shield it from stress and corrosion. The EMC is a viscoelastic material and is categorized as a thermoset. Working with viscoelastic material appose a challenge due to the cure-induced warpage. LÄS MER

  5. 4. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hamidreza Rastan; [2019]
    Nyckelord :Minichannel; Microchannel; Heat exchanger; Additive manufacturing; 3D printing; Numerical simulation; CFD; Comsol;

    Sammanfattning : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.

  7. 5. Simulating Quantum Cascade Lasers with the Position and Energy Resolving Lindblad approach

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Maitane Muñoz Basagoiti; [2019]
    Nyckelord :quantum cascade lasers; quantum transport; simulations; electron transport; Physics and Astronomy;

    Sammanfattning : Over the past two decades, Quantum Cascade Lasers (QCLs) have become an increasingly popular source for mid-infrared and terahertz radiation. Nowadays, their experimental development progresses fast with the aid of computer simulations. These reproduce carrier dynamics in the gain medium of the laser based on different transport models.
